  • Erin Tranfield obtained her PhD at the University of British Columbia in Vancouver, Canada. Her thesis focused on the ultrastructural changes of atherosclerotic plaques following exposure to fine particulate air pollution. Her first post-doctoral fellowship was at NASA Ames Research Center in Moffett Field, USA where she studied the toxicity of lunar dust. Her second post-doctoral fellowship was at The European Molecular Biology Laboratory (EMBL) in Heidelberg Germany where she developed protocols to study the ultrastructure of the meiotic spindle of Xenopus laevis. Erin joined the Instituto Gulbenkian de Ciência in 2013 to first build and then run the Electron Microscopy Facility.

    Erin has more than 15 years experience with electron microscopy, particularly high pressure freezing and automatic freeze substitution, electron tomography and three-dimensional data acquisition. Within the Electron Microscopy Facility, Erin works with the technical staff to train users, maintain equipment and to determine the protocols needed to best address the scientific questions of a given project.

    If you have any questions about the equipment available in the EM Facility, about the opportunity to use the facility or potential collaborations please contract Dra. Erin Tranfield. If you are interested in tours of the facility for schools or interested groups, please refer to Science at Schools.
